The questions you're asking hint at something that could be very
similar to a library or two I've been working on in my spare time.
I've been working on a service library for dispatching functions
between a realtime thread and a set of non-realtime threads, and
vice-versa, and intend to start work on another library that uses the
former to do realtime disk-streaming.

Care to share more details on what you're working on?
